561KD14 Equivalent & Substitute Parts

Part Overview

The 561KD14 is a metal oxide varistor (MOV) manufactured by YAGEO, classified as a Transient Voltage Suppressor (TVS) device. This through-hole disc varistor is designed for single-circuit transient voltage suppression applications with a nominal varistor voltage of 560 V and a surge current rating of 6 kA. The component is currently in active production status and maintains full inventory availability. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to component availability constraints, procurement lead times, or inventory management considerations.
